OBSTETRIGAL DEVICE.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed December 17, 1909. Serial No. 533,694.

T0 all wko/m, t may concern:

Be it known that I, JOSEF STGER, a subject of the German Emperor, and residing at Munich, Germany, have invented certain new and useful Improvements in Obstetrical Devices, of which the following is a specilication.

The present invention has reference to a device for facilitating child birth, and relates more specifically to a device for the purpose indicated, which shows several important advantages over similar apparatuses of this kind, being readily transportable, easy to operate, cheap in manufacture, not subject to repairs, and by means of which the supported weight is borne by a part of the device, and not, as heretofore, by an attendant, who obviously will soon tire, and whose services could be used to much better advantage in the sick room; and the device essentially consists of a pad carrying lever, which is to support the laboring woman at about the small of the back, so pivoted that its operating end can readily be raised or lowered, and then secured in the desired position.

In order to make the invention more readily understood, I will now describe it with reference to the accompanying sheet of drawings, in which the figure is a side elevation of the device.

In use, the device is placed on the bed or on a special support, laterally of the body of the woman, the padded free end of the lever extending underneath and supporting the lower end of the spine, and the pad end is raised, as now to be described, elevating correspondingly and bending the spine upward at the hip region, and thus greatly reducing the pains of the labors.

Referring to the drawing, the doublearmed lever a is pivoted in the up-standing bracket c and carries at l its free end the pad Z2. The other, shorter end is loop-shaped as at a1, and an internally threaded sleeve 7L by means of a stud coperates with this loop. The sleeve 71, engages the external thread of the rotatable spindle d. The parts c and el are supported by the plate e, which may be provided with claws k, by means 0f which the device can be secured to the bed panel Z. Upon the screw spindle being rotated, the pad end b of lever a; is correspondingly raised or lowered.

Over other apparatus, serving the same end, this device presents the great advantage that the weight of the body on the pad is taken up mechanically, and need not be counteracted by an attendant. The latter consequently has only to adjust the apparatus, and is then free to help in other ways. Furthermore, the mechanical pressure is far more steady and consequently more agreeable and helpful, than the irregular manual pressure exerted by an attendant.

What I claim as new isz- In an obstetrical device, a plate, a lever pivotally supported intermediate its ends from the plate, the long arm of the lever carrying a pad and the short arm of the lever having its ends formed with a loop, an internally threaded sleeve having a stud which projects into the loop, and an eXteriorly threaded rotatable spindle disposed at an incline to the plane of the plate and having its inner end securedto this plate, said spindle extending through the sleeve in engagement with the threads thereof and adapted on rotation to move the sleeve along its length and thereby raise or lower the.

shorter end of the lever.

In testimony whereof I affix my signature in presence of two witnesses.
